JOSIAH STUBBS, OF DUBLIN, INDIANA.

CHURN.

Specification of Letters Patent No. 24,678, dated July 5, 1859.

T 0 all whom it may concern:

Be it known that I, .IosmH STUBBs, of Dublin, in the county of lVayneand State of Indiana, have invented a new and useful Improvement inChurns; and I do hereby declare that the following is a full and cleardescription thereof, reference being had to the accompanying drawingsand to the let'- ters of reference marked thereon and made to form apart of this specification.

My invention relates to the construction, arrangement and operation ofhinged dashers, within churns, by means of which great facilities areafforded in churning as hereinafter set forth and described.

In reference to the accompanying draw ings. Figure l is a riew of theexterior of the improved churn. Fig. 2, is a plan or top view of thechurn, the cover being removed in order to show the arrangement of thedashers. F ig. 3, is a vertical sectional elevation of the churn showingspecially the manner of operating the dashers.

(A) represents the shell of the churn provided with stay pieces (a).

(b) is a central bar, the ends of which are made with slots, shown inFig. 2, which are fitted to and made to slide upon the stay pieces (a).This bar (b) is adjustable vertically by means of notches (a) of thestay pieces (a) and the set screw c.

Hinged to the bar are two dashers (cl, d) made with projecting flanges(e) and formed to fit loosely within the shell (A) these dashers (CZ,CZ) are operated by means of rods (g, g) and crank (h) (1).

The operation of my invention may be described as follows: The fluid tobe churned will be placed in the shell (A), and the bar (b) will beadjusted with reference thereto in such manner that said bar may bebarely covered with said fluid. Vibratory motion will then be impartedto the dashers (d, d) by means of the crank (L, k) and rods (g, g). Asthe dashers are forced downward the fluid will rush with great forcearound their outer edges against the shell (A) thereby securing acertain degree of concussion which greatly facilitates the process ofchurning. As the dashers are drawn upwardly, a portion of the fluid willbe retained upon theln, by means of the flanges (e) and thrown violentlytogether as the dashers reach their upper extremity of motion, therebyrupturing its vessels or globules and securing great advantages in therapidity of churning.

That I claim as my invention and desire to secure by Letters Patent is-()perating the butterfiy wings CZ and ci, with the single crank, 7c,confined to one side of the cylinder (g) being made to cross the body ofthe cylinder obliquely to edect this movement in the manner and for thepurpose set forth.

In testimony of which invention I have hereunto set my hand.
